Explanation / Answer

Probability of an event = frequency of that event occurring/ Total number of events

a. probability of the fatality resulting from fall = 645/4535 = 0.1422 or 14.22%

b. probability of the fatality resulting from a transporation incident = 1795/4535 = 0.3958 or 39.58%

c. least cause of fatality is Fires and explosions(113)

probability = 113/4535 =0.0249 or 2.49%

Cause Number Transportation Incidents 1795 Assaults and violent acts 837 Contacts with objects and equipment 741 Falls 645 Exposure to harmful substances 404 Fires and explosions 113 TOTAL 4535
